[0068] As described in the background section, in related technologies, manual sampling is generally used to test the viscosity of slurry. During testing, the slurry stirring needs to be stopped, and a small amount of slurry is manually removed from the stirring chamber using tools for viscosity testing. After the viscosity test, the tested slurry is manually poured back into the stirring chamber. This manual testing method has low operational safety, cannot perform real-time slurry testing, has a long testing time, low automation, high labor intensity for workers, and is prone to missed detections, easily affecting production. While some existing testing structures can achieve automatic testing, samples from multiple tests tend to accumulate in the testing chamber, affecting the accuracy of viscosity testing and impacting the final performance of the lithium battery cathode material. Furthermore, the sampling of the test material and the recovery of the sample after testing are not smooth, affecting the normal operation and efficiency of viscosity testing.

[0069] To address the aforementioned technical problems, this application proposes a viscosity testing device. The device includes a mixing tank, a testing tank, a first pipe, a stirring component, a viscosity meter, and a drive pump. The mixing tank contains a mixing chamber, and the testing tank contains a testing chamber. The first pipe contains a feed channel, a conveying channel, and a water inlet channel. Each of the feed channel, conveying channel, and water inlet channel includes a first end and a second end arranged opposite to each other. The first ends of the conveying channel, the feed channel, and the water inlet channel are interconnected. The second end of the conveying channel is connected to the testing chamber, and the second end of the feed channel is connected to or isolated from the mixing chamber. The second end of the water inlet channel is used for water inlet. The stirring component includes a stirring part inserted into the mixing chamber to stir the slurry in the mixing tank. The second end of the feed channel is connected to the mixing chamber, and the stirring part is located within the mixing chamber. During internal rotation, the stirring unit drives the slurry in the stirring chamber into the test chamber, eliminating the need for an additional drive structure and saving costs. The viscosity tester is inserted into the test chamber to perform viscosity tests on the slurry. During viscosity testing, the stirring unit does not need to be turned off, improving stirring efficiency. The inlet of the drive pump is connected to or isolated from the test chamber, and the tested slurry flows out of the test chamber. Multiple tests can be performed in real time, resulting in a high degree of automation, high testing efficiency, reduced labor intensity for workers, prevention of missed tests affecting production, and good safety. The first pipeline, including a water inlet channel, can introduce water to clean the material passage and test chamber, preventing excessive slurry from remaining in the material passage and test chamber and avoiding errors in the next viscosity test result caused by slurry remaining in the material passage and test chamber, thus improving the accuracy of slurry viscosity testing.

[0107] In some embodiments, reference Figure 4The viscosity tester can be a rotational viscosity tester. The viscosity tester 6 can include a rotor 61. The rotor is inserted into the test chamber. The rotor 61 can rotate within the test chamber. Specifically, the rotor 61 can be inserted into the test chamber through a second opening.

[0108] The rotor's rotation axis can be set along a first direction. This first direction can be parallel to the height direction of the test tank. Alternatively, the first direction and a second direction can be parallel.

The first driving component can be connected to the top end of the rotor. The first driving component can be a drive motor, and the output shaft of the drive motor is connected to the rotor.

[0110] When testing the viscosity of a slurry, the rotor is inserted into the slurry to detect the resistance encountered by the rotor as it rotates in the slurry. The viscosity of the slurry is then calculated based on the resistance encountered by the rotor as it rotates.

[0111] refer to Figure 7 The viscosity tester 6 includes a resistance test module 63. The resistance test module 63 is capable of detecting the rotational resistance of the rotor.

[0112] refer to Figure 7 The viscosity tester 6 includes a data processing module 64. The data processing module 64 is capable of acquiring the rotational resistance of the rotor, and can calculate the viscosity of the slurry based on the rotational resistance of the rotor.

[0116] In some embodiments, reference Figure 5The viscosity testing device 100 includes a drive pump 7. The inlet of the drive pump is either connected to or isolated from the test chamber. When the inlet of the drive pump is connected to the test chamber, the drive pump drives the slurry or water in the test chamber to flow out of the test chamber. By setting up the drive pump, the slurry or water in the test chamber can flow out of the test chamber, achieving a high degree of automation.

[0117] By setting up a stirring component, a first pipeline, a test tank, a viscosity meter, and a drive pump, the first pipeline, including a feed channel and a discharge channel, allows the slurry in the stirring chamber to enter the test chamber without the need for an additional drive structure, saving costs. The viscosity meter detects the viscosity of the slurry in the test chamber. During viscosity testing, the stirring component does not need to be turned off, which improves stirring efficiency. After testing, the slurry flows out of the test chamber, enabling multiple tests in real time. This method has a high degree of automation, high testing efficiency, reduces the labor intensity of workers, avoids missed detections that affect production, and ensures good safety.

[0118] Water can enter the test chamber sequentially through the water inlet channel and the material passage channel, and then the water is discharged from the test chamber to clean the material passage channel and the test chamber. This prevents excessive slurry from remaining in the material passage channel and the test chamber, thus avoiding errors in the next viscosity test results caused by the slurry remaining in the material passage channel and the test chamber, and improving the accuracy of slurry viscosity testing.

[0119] The outlet of the drive pump can be connected to or isolated from the mixing chamber. When both the inlet and outlet of the drive pump are connected to the test chamber, the drive pump drives the slurry in the test chamber to flow back into the mixing chamber. By connecting the outlet of the drive pump to the mixing chamber, the slurry in the test chamber can be returned to the mixing chamber, achieving a high degree of automation, enabling slurry recovery, and avoiding waste. The drive pump can also drive water from the test chamber to the mixing chamber, requiring less water for cleaning the material passage and test chamber, and diverting water into the mixing chamber will not affect the slurry within the mixing chamber.

[0120] In some embodiments, reference Figure 5 The viscosity testing device 100 includes a water pipe 42. The water pipe 42 is used to connect to a water source. A water passage 421 is formed inside the water pipe 42.

[0122] When the inlet valve 52 connects the second end of the water passage and the inlet channel, water can sequentially pass through the water pipe, the inlet valve, the inlet channel, and the material passage into the test chamber to clean the material passage and the test chamber.
